Reverse Input Current
IWS DC/DC converters offer excellent regulation and
isolation in an industry-standard package. Available in
several input versions, the IWS is perfect for industrial,
datacom, or telecom applications. The IWS features short
circuit protection and 500 VDC isolation. Please see the
IWD series for dual-output applications.

DESCRIPTION
FEATURES
Efficiency vs. Load (12V Input)
Efficiency vs. Load (5V Input)
1Continuous short-circuit protection is provided. Long-term continuous
operation in this mode is not recommended. Converter will auto-restart
once fault has been removed.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please
consult factory for specific model information.
